Solar photovoltaic technology has great potential . Among the photovoltaic power generation system , in order to improve the photoelectric conversion efficiency of the solar cell , the design of an effective optical system , and to determine the proportion of certain converging together , the divergence of the solar energy , improve the density of the irradiated to the photovoltaic cells on the fluence , so that the light irradiated on the solar cell in the guarantee under normal photoelectric conversion requirements , achieve high aggregation , high energy, so that the doubled output power of the photovoltaic cell , thereby improving the photoelectric conversion efficiency . Variety of optical system designed according to the principle of non-imaging optics , analysis of the technical characteristics of each optical system , to meet the different needs of different environments , temperature, location . Concentrating photovoltaic systems , choose the condenser . Achieve a high optical efficiency, preferably spot uniformity to meet the unique requirements of the concentrator photovoltaic system . After comparative analysis of the Fresnel lighter its weight , small size , low cost , easy array to its own advantage , become more concentrator concentrator photovoltaic systems referenced . This article will focus on the analysis of the Fresnel lens concentrating photovoltaic systems .
